Motor fuel



Patented Dec. 13, 1932 UNITED STATES PATENTi OFFICE CHARLES '1. RIGHMAN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOB, BY DIBEST AND MESNE ASSIGNMENTS, F ONE-THIRD T0 WILLIAM C. KUHN AND ONE-THIRD IO PETER J. SMITH, BOTH OF PHILADELPHIA, PENNSYLVANIA MOTOR FUEL R0 Drawing.

This invention relates to improvements in motor fuels, I

The primary object ofthe present invention is to provide animproved motor fuel having alcohol as the basis thereof, and pyroligneous acid as an important ingredient which serves to-reduce the specific gravity of the alcohol and makes it possibleto use an alcohol of approximately 130 proof.

Another object of the invention is to provide a motor fuel which will be completely consumed, thereby eliminating carbon and carbon monoxide gas from the engine. With this fuel a development of from to 50% more power is had than with gasoline or other fuel mixtures as a result of the high explosive and complete. burning qualities of the fuel. 1

While any means may be employed for producin the alcohol used, it has been found that alco 01 may be economically produced by starting fermentation in a suitable mash by adding alcohol thereto instead of allowing the alcohol to develop by the slow natural fermentation which would take place according to the usual method. By this process of using the alcohol as the fermentation starter the complete fermentation of the 80 .mash is accomplished in a relatively short period, or in ap roximately twenty-four hours, and the mas may be employed after removal of the alcohol therefrom for food purposes.

In preparing a gallon of the fuel acc rding to the present invention approxim tel 2 ounces of the pyroligneons acid is adde to 126 ounces of ethyl alcohol. Other formulas may be employed without reducing the efiiciency of the fuel while at the same time rendering the alcohol unfit for drinking. For example, any one of the following six formulas may be employed in addition to the formula already given, which formula may be designated FFormula 1.

As previously stated, the pyroligneous acid with the alcohol gives a fuel superior to alcohol of high proof, making it possible to use an alcohol of approximately 130 proof. The other ingredients also add to the combustible qualities of the fuel and at the same time denaturize the alcohol.

While alcohol of 130 proof has forth in the specification as the strength employed, it is of course to be understood that this only represents the proof which has shown the best results thus far Therefore,

it is not to be understood that the invention been set 1 is to be limited to the use of an alcohol of this proof. It is also to be understood that while a means has been described for producing alcohol from mash, any form of alcohol may be employed such as ethyl, methyl, butyl, etc. Also, gum camphor may be employed in place of the spirits called for in the formulas given.

Having thus described my invention, what I claim is:

1. An improved motor fuel consisting of alcohol of a proximately proof, pyroligneous aci and camphor, the acid being employed in the proportion of approximately 2 ounces to 126 ounces of the alcohol.

2. An improved motor fuel consisting of 1 alcohol, pyroligneous acid, and camphor.

3. An improved motor fuel consisting of aliZOhOl, pyroligneous acid, camphor, and an 01 4. An improved motor fuel consisting of alcohol, pyroligneous acid, camphor, and a vegetable oil.

5. An improved motor fuel consisting of alfiohol, pyroligneous acid, glycerin, and camp 6. An improved motor fuel consisting of alizohol, pyroligneous acid, camphor, and fish o in twtimony whereof I hereunto aflix my signature.
